      abstract     = {Collective behavior of active matter is observed for
                      self-propelled particles, such as vibrated disks and active
                      Brownian particles, as well as for cytoskeletal filaments in
                      motile cells. Here, a system of quasi two-dimensional
                      penetrable self-propelled rods inside rigid rings is used to
                      construct a complex self-propelled particle. The rods
                      interact sterically with each other and with a stationary or
                      mobile ring via a separation-shifted Lennard-Jones
                      potential. They either have a sliding attachment to the
                      inside of the ring at one of their ends, or can move freely
                      within the ring confinement. We study the inner structure
                      and dynamics of the mobile self-propelled rings. We find
                      that these complex particles cannot only be characterized as
                      active Brownian particles, but can also exhibit cell-like
                      motility: random walks, persistent motion, circling, and
                      run-and-circle motion.},
